This little utility grabs the hands as they're saved by your EPN client and converts them to PokerStars format. Then it saves them to wherever you specify. Next HM2 imports those hands as if they were original Stars hands. Finally, you use HM2's table finder to connect the tables from your active session to the actual table windows and your HUD appears like magic!
Since EPN has no persistent preferred seating it will get a little tricky. For me what worked is to make sure you have no preferred seat set for 10 max stars tables in HM2's Site setup. Then when the panels appear in random places just drag them to the right place. After that everything worked fine. You could probably set a preferred seat in HM2 and then just click "sit here" in EPN if you want but I find it too hard to play more than 4 tables here anyways.

It is free for now. I don't know if it will be forever but if people get value from this and it takes up time for me to maintain then I will end up charging a small amount.
If you are worried about downloading a zip file and running an .exe from some random website then hopefully I can get you to trust me by saying I also made one of the apps that runs natively in HM2.
LIMITATIONS
I haven't been able to get this working well with PT4. The hands import fine but the HUD doesn't stay on the table very reliably. As far as I know PT4 doesn't have an equivalent to the table finder. It does detect the table and attach the right HUD but then, like a young boy with a crush on an older girl, scurries away timidly.
EPN doesn't give particularly complete information for SNG/MTT. Not only are winnings not included, neither are buy-ins. Therefore, all SNG/MTT are converted as $0 + $0. You will have to edit them in HM2
I only tested this on full flush poker. I imagine it will work on other skins but I can't say with total certainty.
