Default Anyone running a true drysump setup with remote oil tank?

I have been looking into running a custom sump pan with a peterson 3 stage drysump pump, remote external oil tank.
I would then modify the original oil pump so it has no internals and use it only as a cover for the front of the engine (after blocking the respective oil passages).

I am thinking this setup will resolve a few issues-
1/ No chance of aerated oil getting into the oil supply
2/ Increased engine sump vacuum level
3/ Increasd engine overall oil volume
4/ Ability to better control and alter oil pressure
5/ Reduced sump pan size allowing for custom short length headers
6/ Overall improved reliability of engine oil supply at high rpms and cornering.
7/ Relocate oil filter to allow more room for headers (and easier changing access)

My only concern over this setup is the reliability of the pump drive belt which would be a HTD type (same type as timing belt but smaller). I wouldn want to have the belt fail or need to change it every 5000kms.

I would like some feedback from other people that may be already doing this.
Anyone out there ?
