any ideas where i could find a cloak to go over a thobe?

jazakallah...

The closest resemblance to a cloak is a Moroccan style jallabiyyah. It's got the hood and everything. Put that on over a thawb and you'd be looking like Obi Wan Kanobi.

Ask a Moroccan brother in your area for details.

They look similar to these (prices are sorta ridiculous, better to get them from overseas):
