Pool Temp a few degress too cold

Hi. I have found that the usual pool temp of 78-80 F at the pools I use now seems a couple of degrees too cold for me. Due to medical issues, I am now very sensitive to the small temp difference, enough so that I will stay out of the water being it feels too cold. I have always swam in a brief suit, but now wondering if a kneeskin or body skin might provide just enough boost to raise the temp a degree or two. By covering more of my body, the water might feel just a bit warmer. There are triathlon suits out there that provide insulation, but those are really made for cold water swimming and I don't want to restrict my form by wearing a bulky tri suit and a tri suit would probably add too much insulation and I would end up overheating. Anyone have any thoughts if this idea would work? I have no experience with a kneeskin or bodyskin. If a kneeskin or bodyskin would warm me up just a couple of degrees, it would get me in the pool much more often. Thanks.
