MF-02 might be the cheapest host capable of doing it with XHP35. Too bad that it throws far enough stock, but if this really bothers you, you can just replace its components with your own.
Though a different LED might open some possibilities.
I suggest that you consider SST-40, it’s much better than XP-L HI. Osram Q8WP is a nice option too.
