Automatic transmission oil pan modification

Hello, I have a custom made car with a house made chassis. I've been driving it successfully with a dog ring manual gearbox.

I now would like to switch to an automatic transmission. The smallest gearbox being able to handle 460Nm/340ftlb of torque that I could find would stick 3cm/1" under the flat floor of my car. I can't raise the transmission or the engine.

My question is: Is it possible to remove the factory oil filter located in the bottom of the oil pan, flatten the oil pan and then place an external oil filter system?

Why not modify the floor of your car?

The floor would already have a hole for the transmission but it would still stick out by about 3cm/1".

I may have to design a skid plate to protect the oil pan from bottoming out. But that will only come if i do not find any solutions.

The gearbox I am currently looking at is the TCI 6 speed gearbox (http://www.tciauto.com/tc/6x-six-speed-transmission-package-optional-bellhousinghtml):

I'll design my own bellhousing to fit that gearbox to my engine.
