That seems easy enough to try. Tomorrow morning I'll try this, adjust the pedal up a tad (its currently level with the brake pedal so I think I can get away with raising it an inch or so, and change out the trans fluid. I need to change out the trans fluid anyways as part of the trans break in. Hopefully some of this will help, if not I can deal with a slow second gear until I have time to pull the tranny for another rebuild, I've dealt with it for 7 years already, whats a couple more 😁The other problem that can get you is if you measure you'll see that the MC likely slopes slightly up to the front of the car (and it definitely slopes up when you've got the front jacked up to do a bleed). Thus you can get a bubble of air in the front top of the cylinder that is difficult to get out.
What I do is bleed the clutch normally first at the slave. Then I lower the front, jack up the rear of the car really high, and jiggle the clutch pedal for a while. This moves the bubble to the rear of the MC where it can escape into the reservoir...you'll likely see some tiny bubbles when you do this.
