Sure, anything is possible with a little imagination and work..

.....On my 65 Fastback, I put the
oil pressure and
oil pressure warning light on the same "circuit", so to speak.......What I did was come off the factory location on the block with a very short piece of pipe, then added a T, on one end is the
oil pressure light switch and the other end goes to the mechanical oil pressure gauge on the dash......
I suspect you could put the oil temp sender here also, (mine already had the bung in the pan so I used it), might be a tight fit,get some fittings and "mock it up" first and see how it turns out.....
On my race car (small block ford) I put the oil temp sender on the remote oil filter, most if not all have a port for the oil temp sender on the top of the remote filter housing, very clean job and easy to get to, an alternative if you have a remote oil filter..........
