Rhododendrons: Azalea grafting question ?

Hello All
I live in the Tallahassee Fl. area, and have been into bonsai for about 15 years.
I found an azalea at an local nursery that had beautiful roots and trunk ( for a bonsai )
it is a R Indicum " Nathan Bedford Forrest ". The label read Large leaves and large orange flowers.
The large leaves and flowers wouldn't be good for a bonsai, but I thought I can approach graft some of my small leafed / flowers from some of my kurume azalea " coral bells " onto it. So I bought it.
It occured to me later, that I'm planning to graft an evergreen branch onto a deciduous trunk.
Will this work. I 'm wondering if the dorment roots and the evergreen leaves can work together.
Bonsai folks so far , just don't know , hopefully some of you guys can help me out.
Thanks for any thoughts and help in this.
