LUK ITS A FUZBALL
Would it work out?
Of course, a minimum of two if possible to fit them.

if you can find a good breeder then there most likly not even inbred.
yeah buy your females from one shop and males from another then your fry should be healthy. Remember 3 females to 1 male will help ease the stress
You won't have room for a vast amount of fry in that tank. The other consideration is that the females may well be pregnant already from the shop so for the first few batches you might not have that much say about paternity. On the other hand, an all male community might suffer aggression problems in a smallish tank.
I think if I were you I would go for an all female community- they tend to be more peaceful IME and eventually the supply of babies will dry up. I like female livebearers anyway- they have all the outgoing attitude and charm without the hormones.
Other suggestions might be:
livebearers (if you can find them)- endlers, heterandria formosa (least killifish/dwarf livebearer)
barbs- cherry barb (1 male+harem)
tetras- small tetras: neons, glowlights, black neons (there are loads more, but I'm not much of a tetra person), ember tetras if you can find them
rasboras- harlequins, espei or some of the dwarf rasboras if you can find them
oddballs- peacock gobies (1 male+harem)
