Yup, I use my PVA glue on the glass to print both PLA and PETG with no rafts. It makes a huge difference. I would expect it to work well with PVA filament too. HIPS im not sure about as I havent tried printing it myself, but I would say its definitely worth a shot. I make a mix of 5 parts water to 1 part PVA glue, put a small blob on the center of the bed (maybe 2-3 ml) and then spread it around evenly with a cloth. If you apply it to a hot bed it dries in minutes. I then give the surface a quick wipe with methylated spirits to remove any greasy finger marks before each print. The PVA film lasts for many prints without needing to be reapplied. I also run my bed a lot hotter than you which might be relevant. I print PLA at 80degC (which gives me about 60degC on the surface of my glass) and PETG at 100degC (so about 80degC on the print surface).
