I've always viewed the Magus and Warpriests as mirror versions of each other, in that they both allow you to combine magic and attacks with your action economy. Arguably, the Magus does it better, but that's besides the point. Let's see if we can combine them in the weirdest way possible.
Race: Undine
Point-Buy 18 WIS, and get Guided Hand with a longbow since the Warpriest gets Channel Energy.
Using the above strategy, it might even be worth it to actually use the aging rules if you have a 25-point buy.
If you go old:
STAT Point+Age+Race=Level One Stat
STR 15-3-2=10
DEX 7-3+2=6
CON 13-3+0=10
INT 14+2+0=16
WIS 18+2+2=22
CHA 7+2=9
Take the Eldritch Archer and Kensai archetype, in order to use your bow and to get INT to AC. This will balance out the DEX of 6.
Take the Sacred Fist archetype, in order to get WIS to AC.
The result is hilarious. A old undine with shaky hands (6 DEX) that walks with a cane...
...that becomes Legolas the instant he starts holding a bow.
This is definitely something to play if you're starting at a level other than one. Or if you're playing with a bunch of new players, so the DM isn't being vicious and you just want to fool around with good RP:
(old water-man with cane talking to 20 year-old half-orc barbarian.)
"What do you mean, you don't think a wand of cure light wounds is worth it!?! Young man, do you you know how many times I've saved......"
Have his traveling companion be an aging Barbarian/Pirmalist-Bloodrager with the SPRING RAGE Rage Power.
The best version of this would be an Arcane Bloodrager who swaps out their level 12 Bloodline Power for Rage Powers, but getting through levels 1-11 would be a huge slog.

It'd be thematically appropriate to a fey bloodrager, and they can lose their 4th level power without regretting it. Confusing the enemy sounds right too.
One possibility to consider: magus 5/warpriest 2 (to pick up Fervor)/magus +3 (to pick up Broad Study and Reach Spellstrike)/warpriest +2/mystic theurge 8. Adding the cleric buffs (such as divine favor, using Fervor to cast it as a swift action), healing spells, and the spontaneous inflict spells (neutral warpriest worshiping Nethys?) can improve the character's staying power and (using Spell Blending to pick up heroism) counteract the BAB hit from mystic theurge.
Yeah going Magus-6/Warpriest-4/Mystic-Theurge-10 (in whatever order suits you) for Broad Study is probably a good idea.
It's worth noting a couple of limitations though:
You'll be focusing at least 3 stats (INT + WIS + STR/DEX), which makes you a little more MAD.
Ferver increases with level, and won't increase with Mystic theurge. Also there is no "Extra Ferver" feat, so you'll have to pick when you go full nova.
Finally your Arcane Pool enchantments won't increase with Mystic Theurge, so you'l only be getting +2 from that. The biggest increase is at level 5, so that's 100% worth it, but you won't get quite the buff that high level Magi get (you will get 5th level Cleric spells though, so it should even out).
