I would also like a way to tip studios, some scenes are so good and underrated I've felt like leaving a tip sometimes.
Custom videos can be quite expensive for professional studios to make, as they have to pay the actors etc.
They work much better for amateur couples, as they don't have any costs for the production other than time.
So, for how SLR is today, I don't see this working very well if at all.
Before considering custom videos I would try expand the site to invite more creators, if you could think of a model to invite them in like some sites have already done with camgirls.
Speaking of camgirls, this might be something that could actually work, if you find a way to let users record by paying tokens... I think some sites have this option, maybe not for all models, but they let you keep recordings of private shows if you pay.
Well, wouldn't this be making a custom video already? Just need a way to record and save the recording.
I think that for now, setting up ways for it is good enough, for example, letting us open chats with studios and also make donations.
Users could already try and make customs at their own risk, by chatting with the studios directly and eventually donating
