[WH40K/Star Trek] How long would it take for just a couple of Orks to completely overrun the Star Trek universe?

If a few fell out of the warp and crash landed on some random planet, and the spores took hold, how long would it take before they just overran everything? Months? Years?

I'm speaking from the point of view that nothing in the Trek universe could really stop them cold. Especially once they managed to loot a Borg cube and made it Orky.

Sadly, the Orks can't do anything, as their FTL tech relies solely on the Warp, which probably doesn't exist in the Star Trek universe. The best they could do is make a planet or system ridiculously dangerous. Assuming the can get ahold of FTL travel somehow, it would take a year or so to get a steady population and around 50 to overrun the universe. There seem to be a ton of populated planets, but they could probably find and destroy the major ones in 10-15 years, but it would take a long time to get the small ones.
