Unfortunately, not before the females will be dropping more fry. I have the same hassle with Endler's. I keep moving out the colored-up adults to make room for growing fry. I tossed class N fish from 3 different sources together to mix their bloodlines, so you never know what will come up next.
Guppie BABIES!!! :D

Ahhh the joy of live-bearers.
Had the same issue with Guppies and Swordtails when I was a kid... blinking things wouldn't stop breeding- and as a kid I felt it my mission to save all the babies from the parents- so I ended up with 100s of the things and kept trying to give them away.
Once I went with all males- but one of the males got pregnant... ... babies. (perhaps it wasn't a male afterall
)
Several years later keeping them again, this time I got all females- but one of the females were already pregnant when I got her... babies.
Thing about guppies. Females are not normally as colourful- but if you keep males in a community tank they can harass other fish- even of different species because they have an insatiable desire to mate. They're like fraternity brothers after a keg of beer and a quick flick through an adult magazine... they'll try to breed with anything with 2 or more or fewer or no legs.

I've heard before that swordtails can switch sex if there is a single sex school, but that may have been an urban legend.
What would be an interesting scenario.
Buy one male and one female feeder guppy from a store. Place in a 300 Gallon aquarium. See how long it takes for Guppies to max out the bioload... (about 200 Guppies?)...
... insert a pair of large Cichlid.
See if the Cichlids can eat the guppies faster than they can reproduce.
See how long it takes for predator to wipe out the guppies- or can the guppies sustain a population whilst being eaten.
NOTE: I wouldn't actually do this... I'm a bit of a softy when it comes to fish... I'd never feed a fish to another fish... would be interesting to know how long the guppies would last though.

It's never been reliably observed for a functional male to become a functional female, or vice versa.
... and I'm not going to claim mine did either... I was young at the time and very likely made a mistake of what was a male and female. I thought I had single gender.
I'm not going to rule out sex-change- nor would I rule out I screwed up. Both are possible.
My grandmothers female swordtail changed sex to a male. She never gave birth again and IT became her last surviving fish. I just got 3 large female swordtails so I might find out soon if this is in fact true.
