All,
Thanks for the replies. I have decided on the following, like ZRAYR advised, with a couple of mods:

changing the 69 primary to a 68, the secondary from a 77 to a 75, and the power valve from a 6.5" to a 7.5".

The jet changes will be lean out the mixture, and the power valve will be to get it's fuel in sooner, hopefully easing the transition when the secondary circuit comes in.

I will let you all know how it turns out.
