I figured that I can hold the D7 an extra beat and then make a single note run of D-E-F# and then back to the 1.

...but I should be able to harmonize the one note bass that follows the progression forward as well.

I should be able to harmonize the whole thing G-B-C-C#-D-(what's there so far)and then on to-Eb-E-F#-G

OR I should be able to go G-B-C-C#-D-(what's there so far)-and back down to-C-B-A-G
