Modifying Turn Undead Level

Hello all,

I'd like to know how to modify the Turn Undead skill of the Undead Hunter Paladin. To boost this kit a bit, I'd like to be able to Turn Undead like a cleric of the same level. I'll also give him Remove Paralysis as an innate ability, thus copying the benefits of the Ghosthunter of the 2e Paladin Handbook. That way, Undead Hunters get thematic benefits that boost their ability without being OP.

I tinkered around with EEkeeper and NearInfinity, but, since I'm not yet very savvy with these tools, a few pointers would be appreciated. Thanks !
