So long as you don't try and use the same markers as different things, ie "No, that red base is a scheme marker, that one is a corpse counter." It should be fine, also, what crews are you using? Some dont need any markers other than schemes, Perdita for example only needs scheme markers (30mm bases are fine), while Ramos would need scheme markers and scrap (30mm as well) but Sonnia with CHeroffe's imprint would need two 50mm markers for flame wall.
