Drunken Halforc SSB questions

I'm currently level 8 (Halforc 2 Oath of Ancients Paladin/6 Swords Bard) on my second character (and first Durge run). My goal is to make a smiting frontliner who uses the Punch Drunk Bastard to do a bunch of aoe attacks with Slashing Flourish.

Currently my base stats are 8 Str (21 with Hill Giant Elixir), 17 Dex (18 with Ethel's hair), 14 Con, 8 Int (17 with the Headband of Intellect), 10 Wis and 16 Cha. I have GWM and am planning on picking up Savage Attacker at level 10.

My equipment is Headband of Intellect, the Durge Invisibility cape, Helldusk Armor, Flawed Helldusk Gauntlets, Boots of Stormy Clamour, Amulet of the Harpers, Malefic Ring (planning on replacing this with the Callous Glow Ring) and the Strange Conduit Ring. I'm using the Punch Drunk Bastard and a pair of Hand Crossbows (a normal +1 and the Ne'er Misser). I'm concentrating on Protection from Evil and Good to get the extra psychic damage. I figured spreading Reverb with the AoEs would be a great way to get some extra benefit out of hitting multiple targets at once. The headband is really only there so I can pass Int checks more easily, I'm not married to it.

Does anyone have any experience with a build like this? I'm currently enjoying it but I'm not confident I'm not stretching the character too thin by trying to combine a bunch of different things into one build. I do very much enjoy being the frontliner, party face, lockpicker AND get to play a very goofy concept that has been a ton of fun to RP so far.
