Stabilize has been adjusted to use a channel, from the person being revived if available, otherwise from the caster. Note that committing channels is likely becoming very expensive as channels are rare and difficult to get more of.

Might be interesting to add a single hp to the recovery buffer as an additional benefit, but in principle works as written.

What does everyone think?

I think that an additional benefit might be reasonable, seeing how a channel commitment isn't a small thing. I like Mercury's proposal, and I'm thinking of augmenting the spell a little further along the lines of:

• Adding a 1hp to the recovery buffer.
• Preventing the target from destabilizing if they take additional damage. The channel commitment is ongoing after all, so the stabilization effect might be as ongoing as well... Say, until the channel is forcibly decommitted as per Energy Channels rules.

What do others think of this?

I have rewritten the spell based on your suggestions

Looks good.
