Feasible formations that make use of 4 (or even 5) attackers?

Because I can't help but purchase the most talented young players available, and it seems that Star regens are disproportionately attackers (primarily attackers, with the occasional attacking mid/ winger), I wanted to make use of a formation that suits my lopsided roster.  I've considered a 4-2-4, but think I can do better.  Similarly, I've considered a formation with 2 strikers ahead of 2 attacking mids, but can't find any combination of roles that wouldn't make such a construction redundant.  The idea in which I'm most confident is a 4-2-3-1, because it allows me to use most of my best players with minimum re-training.  

It would look like this: 

 

 FB(A)                                          IF(A)

BPD (ST)             CM (S)                      

                                                     SS(A)           F9(S)

CD (COV)            CM (S)    

 FB(A)                                          IF(A)

 

I know it may seem too aggressive, but I handily win most league games, and for the most part am merely looking for a way to play my most promising players all at once to give them time to develop.  I will have alternate tactics for more even competition.  

 

My questions are primarily: 

1. Would the opponents third become overly crowded, and would that be at all fixed by converting one of the IFs to a Raumdeuter?

2. Are there any center mid roles that would work better than CM (S)?  I find most of them to be too specific, as I really just want a versatile player there that roams between defense and supporting the attack, but doesn't make the aggressive forward runs of a BBM.  

3. Are the central defender roles a logical pairing?  I want at least one BPD so that I can effectively play out of my defense, and like the idea of specialization with the stopper and cover duties, but would I be better served just leaving them both on defend?

4. Should I stick with this formation, assuming its relatively cogent, or play a little more with 4-2-4/ 4-2-2-2 variants?

I should have added, is there any conceivable way to play with 5 attacking players that doesn't leave my team wholly disjointed?  (expecting the answer to be no, for what it's worth)

Forgive me, please, for spamming my own post.  With that being said, I know that I should probably have one midfielder with a defend duty, and would like to even have a defensive midfielder playing behind a central midfielder, to make what I guess would be a 4-1-1-3-1, but am worried that I would be sacrificing my interplay abilities by having so many lines. Is that a legitimate concern, or no?

I personally would not play like that, but it does not mean it cannot work in FM. So I think you should test your tactic first and see what happens. If it works - great. If not, come back here for some advice

Something I've done at Man United was my high-pressing take on a 433. Standard back 4, one CM on Defend in front (I used Bentancur as a BWM and he was brilliant), then have 4 forwards in the AM strata behind a striker. Can leave the midfield open at times but the attacking midfielders help us press much higher than the standard CMs, and we create lots of very nice chances with our 5 attackers. The defensive record has been really good too, thought I suspect the results would drop off quite a bit if you're not a big side with top players.

4 attackers definitely 4231, 5 attackers id say 352 with cam 2 strikers and couple of wingers or just be brave 2332 (DCR, DCL, WBR, DMC, WBL, AMR, AMC, AML, STx2) Gives a perfect WM shape as for roles and duties just experiment
