Making the novel what you want is a good choice. In terms of commercial, if someone loves it they will either publish at your length or find a way to cut it into multiple parts, maybe padding with short stories if it is too short for a two parter. Also ebooks are not as fussy as printed formats about upper limits. So if something else by gets published first, that could be published in a ebook plus POD format.
Unrelated: a bit of dream dialog last night that was amusing and might be worth someone's while to steal if they wished.
p1) "Vampires are notoriously fond of gossip and scandal."

Any Daily Science Fiction subscribers around here? I sold a short story to them that's going out by email on Monday. It'll be free on the website a week later. At some point, I'll work up the moxy to post that in press.
Congratulations! I didn't know about Daily Science Fiction, now I am intrigued.
It's a lot of fun getting a story by email every day, and the site works well. I don't love all of the stories (I don't love _all_ of them in a lot of pubs), but I love enough that I look forward to seeing what's in the mailbag. The editors are good folks. Granted, I'm biased. They bought two stories of mine this spring/summer. The other will likely appear in/after November.
In other news, who is on Goodreads? I have Raq, Amy, & Barb already ...
I think I said it before, but if not, congratulations on the sales!
Sox, megabelated megacontratulations.
