The short answer is: Focus on recovery only during PCT
During pct your body is going through a pretty extensive recovery phase, dieting in any form is going to produce more stress & make the entire recovery process much more difficult. Not impossible, just more difficult.
Theoretically it should be possible to cut during pct, but until I can see it in action, with the appropriate measurements of physiological changes during the process, I wouldn't recommend it - Barnzy is right on this.
To answer some of the questions you had:
You dont think my recovery will be affected by a caloric deficit? I'll probably go keto so plenty of fats in the diet aswell... Just don't wanna effect my natty test coming back
Dieting DOES, temporarily, reduce testosterone levels.
So combining PCT (were your trying to recover your natty levels) with dieting (reduces natty levels) is a very bad idea on many levels. Whether it would permanently reduce your test levels, I doubt it - it would probably just mean that you need to spend longer on pct & recovery then usual.
Just a thought - is there any way (through more frequent structured refeeds) I could keep Leptin upregulated more often than not, in turn not affecting recovery too much?
Refeeds can upregulate leptin temporarily, the levels will drop again within 2/3 days. So you would need 2 refeeds per week to keep leptin at a decent level; 2 high carb, high maintenance days will wipe out a moderate caloric deficit done during the other 5 days.
In terms of your idea of running a modified PSMF/keto diet, if your doing a refeed 2x week then your not really doing a psmf/keto because at no point will you be fully glycogen depleted or in keto (unless you plan on training 2/3x per day).
Basically, the fat loss results will be really poor, hence not worth it.
