I didn't come up with a good solution on that Thursday. But inspecting it again today I realized that currently it's way above the tire stacks, so it should be no problem to lower the entire oval. I'm just too lazy right now to do it manually.
Might tweak the python script I wrote for my newest idiocyea though to speed this up... xD and I'll do my best to provide slightly higher banks, though I won't increase it too much so it still allows an equal inside and outside for UF1.
