I'm just going to add a couple of things to consider, as I really think you got some great responses.
For a trapmonkey bard this was my take on it originally:

This was before half-elf was around. I recently gave myself a sad turning her into a hagglebot temporarily. I would totally build her again as a HElf with paladin dilly. In fact I will do so if I can ever get my intended hagglebard to cap. She's filling in right now. She was a good utility build, able to heal parties if needed as well as get any trap in the game. Melee was passable, she relied on flanking, but could hold her own soloing. She lacked in high reflex situations though by a hair (Crucible Swim). Pally Dilly and some different feat choices would make that a breeze.
This is my other primary bard, Elkabongg. He's a frankenstein warchanter that is a work in progress. Now I'm still doing feat swapping and such to rework him, but this was my original plan for him:
Starting Feat/Enhancement
Abilities Base Stats Modified Stats

Strength 18 27
Dexterity 9 11
Constitution 16 19
Intelligence 10 12

Since the xpac I dropped a fighter level to gain 15 bard. This gave inspire heroics and access to inspire excellence. Net loss was some hp really and that's about it. Still trying to get the feat swapping right though, Fred is a pain to work with. He's only missing overwhelming crit. Picked up cleave/great cleave in exchange for some other feats. I've very reluctant to LR him to fix everything I want to. So we'll see how this ultimately pans out.
Primary casting bards I've always been ambivalent about. Anything they can do a Wiz/Sorc does just as well or better. So I focus on the song magic with a secondary strong utility. Both of those build plans are not updated btw in reference to MOTD changes. They were the springboards to start from. But they should provide something to consider in your musings.
