You could try having your normal spells set to a [nostance] parameter. Something like:
Code:
/castsequence [target=targettarget, help, nostance] flash heal, renew, greater heal, greater heal; prayer of healing
Basically set it up so your macros all work normally as long as [nostance] is true.

What I can't tell you is whether it sees Spirit of Redemption as a stance or not. Wowwiki doesn't list it as such, so I tend to doubt it. Might go create a simple test macro for that and get naked somewhere (to save repair costs) and try it out.
