Depends if you want a weapon light, and if you do, if you'd have a way you'd want to mount said weapon light. If no, or you have a way you'd want to mount a light then sure. Only other consideration is if you're front wired.

Front ends/handguards are so easy to swap out that it's not exactly like any of this crap is permanent anyway.

Yes out of all the front ends you can have on an ‘older’ looking M4 then the slim grips look the best BUT the minute anything fagpul or ‘operator’ touches the gun it looks naff as fook ! 

The gun is rear wired and I don't think I'll ever mount a torch on it (I don't use torches during night games and I have other guns for cqb).

It's going on my 933, I do fancy a Gordon's Carbine look but with a more practical approach.

I currently have a PTS EPG-C grip because it's more comfortable than the regular A2 and the standard crane stock for battery space reasons, those two are staying on the gun.

The A2 carryhandle receiver looks cool but I can live with the A4 (also lets me use optics without having them too high).

The moe handguard I currently have on is nice but it's boring and the stock M4 plastic one is too chunky for my hands.
