Greetings . . .

If your heart is not set on the Beehive type under hood oil filter - you could go with a 'relocation' kit:
Relo Kit from JC Whitney I
Relocation Kit from JC Whitney II

This would allow you to rig your fittings so that the oil lines stay close to the block (90 degree elbows), routing them down underneath to the frame. With the relo block mounted down there you could use spin-on type filters - and avoid oil change mess under the hood.

I've seen this type of set up on off road and towing vehicles that need oil coolers. They even make relo blocks that take two filters - further increasing the amount oil in the system.

regards,
Keith
