I like the idea but......

The Catch can, being low in position, will eventually collect oil and fills it up. Now oil will enter the I.M.
My suggestion is simplicity: somehow use a snake or something to create a loop that is higher than the Valve Cover, this way any oil that enters the loop flows back down by gravity.
See my earlier post about "snake" on poolman DIY.
