I think Guldo is Ginyu's most important subordinate

Guldo's time freeze ability allows Ginyu to safely swap bodies with stronger opponents instead of risk missing his target. I know Guldo's time freeze is based on range but i also think stronger fighters are less immune to this if they know whats happening.

So a stronger fighter may get caught off guard and that is all it takes for Ginyu to do a body swap few times until he found the strongest body he could which was the purple one (until he fought goku and vegeta he was the strongest fighter after Frieza King Cold and non canon Cooler).

But why did he not power up Guldo so he can extend his time freeze range and duration by swapping him a stronger body, maybe at least from 1 of the other 3 Ginyu members or Ginyu's older bodies?

Wouldnt it be nice if we get a sidestory of Ginyu force? i know there are official joke comics about ginyu but non canon.

Imagine the duo keeps growing stronger and stronger they probably have the highest potential than Saiyans. If they succeeded in swapping with Goku and Vegeta the first place they could just secretly zenkai each other and use the healing chamber to power up faster than Goku and Vegeta having to train hard instead of using senzu vean or dende cheat codes.
