At least as currently defined, the Dresdenverse (ie, WoJ) and RAW (DFRPG) don't allow for any compatibility between magic and all but the most rudimentary technology.  So no -mancies that involve technology, electronics, computers, etc.

Of course, Jim could always change this in the next book, or the book after.  But for now, I think it's pretty clear that tech and spooky don't mix.

You might also want to nail down the list a bit more in terms of powers used (ie, Channeling vs Rituals).  For example, Pyromancy is Channeling(Fire), Ectomancy is Rituals(Ghost theme), etc.  I would probably classify Enchantress as Rituals(Crafting) (ie, turning non-magical things into magical things via enchants), though if you want to include enchantments on people, then you might treat it as a theme, instead.

Also, Psychomancy and Neuromancy are really just Rituals(Psychomancy), since the YS version of Psychomancy covers both reading and manipulation already.

The following homebrew power might be helpful, or it might not. But I figured it was worth posting.

QUASI-MODULAR ABILITIES [-Varies]
Description: You have the ability to alternate between multiple powersets.
Musts: You must "pre-pay" a number of refresh points equal to the total value of each set of powers that this power affects, plus a surcharge of one refresh.
Skills Affected: Varies.
Effects:
Two Powersets. Pick out two sets of powers, each with a total refresh cost one less than the cost of this power. You may use either set of powers, although it takes a full action to go from using one to using the other. The GM decides what is and what isn't a valid choice for inclusion in the powersets provided by this power.

On the other hand, compelling an aspect added by someone else through a manouver can be problematic.

Guh, I would almost ask what the point of all that is. You could take every one of those upgrades for 7 refresh and it's still not as good as taking channeling:fire and merely describing it as the use of fire breath. I guess what I should say is it seems underpowered, but then so does breath weapon.
