gfp and aequorin

I'm very surprised to notice that there's only one
paper on gfp transgenic mice and none on aequorin 
transgenic mice.  I have been thinking
about doing transgenic mice to express aequorin in
brain, in order to study neuronal calcium activity 
on brain slice. Will it be difficult to see it because 
of incubation with coelentarazine, the expression
level may be covered by endogenous fluorescence, also
it may be difficult to have subcellular resolution
on brain slice.   Anyway, what's the difficulty on 
gfp transgenic mice?  Is gfp much stronger than
aequorin? I will appreciate it if anyone could 
give me some suggestions.
