Frankenslotting help

I'm looking at frankenslotting a blaster, and I hit a roadblock: Targeted AoEs. With so few sets to work with, frankenslotting is difficult at best. Can someone help me find the biggest Acc/Dam/End/Rech bonuses possible on both 5 and 6 slots? No purples or PVPs, but Hami-Os are OK. I managed to get ST blasts to 95% Acc/Dam/Rech and 79% End, but can't even come close on the AoEs.

Actually, I'm specifically working towards NOT having any global anything on this character, it's more of a slotting experiment, looking at each power individually. At the moment, what I'm playing with has no global accuracy (except that granted by Targeting Drone) or recharge. The specific powers in question are Explosive Arrow and Rain of Arrows.

And now that I think of it, that's even more relevant, since at least EA can take a second set type, though not necessarily a great one.

I know you said no pvp's, but there are pieces of Javelin Volley (like the D/E/R) that are fairly cheap. I think one just sold for 6 million for the recipe.

I think the best I came up with was A/D/E from 2 sets (Posi/Detonation), D/R from the same 2 sets, either D/E or A/D from one of the sets, and then the D/E/R from JV. I no longer have my Mids open, but the numbers were fairly respectable.

A five-slot variant is harder for me. I often just 5-slot Posi and accept that my recharge is going to stink in the power but that I'm at least getting a global recharge bonus for my trouble. You'd get better values out of 2 Nuc's, 2 D/E enhancers (or a D/E and the JV D/E/R, so you're not pushing the damage quite so far into ED range), and a level 50 recharge IO.
