Why would you want to? Unless you have a special deal with someone who's paying you under the table or you have some other obligation to that operator, that juice just isn't worth the squeeze, drama or, quite frankly, the risk. If you want to make more coin, most outfits have a way of doing that which is guaranteed to be more lucrative.
One day you're going to be at your other job, and you're going to be AOG because reasons, and it WILL conflict with you main gig. Or there's a, god forbid, incident/accident. And that's if you're playing it straight. Knew one guy in a previous life that banged out sick to ferry an airplane and wound up gearing it up. I'll take "conversations you don't want to have for $100".
OTOH, regular GA is fine, but I do chortle a little bit about "there's sooooo much traffic these days". GA operates at a fraction of the size it used to, most places are ghost towns, we have neato ADSB which shows nearly everything out for 30 miles, including position, direction, altitude, airspeed, and N number. We got satellite or FIS weather, internet weather briefings and WAY more information than we ever had back in the day including Google pictures of the airport. Cell phones for clearances and GPS good down to the meter with detailed moving map displays. I get the SE engine worry, but we also now have engine monitors that watch every aspect of the engine performance.
I won't get into "back in the day", but we had none of that, and somehow survived.
