With the adjustments to forestay and step position, you'll probably be needing more upper tension than last year.
Once you have enough upper tension, you may find your backstay quite floppy, even with the backstay turnbuckles maxed. The standard backstay was usually cut too long for this sort of tuning. You'd probably have to put quite a bit of backstay on before it does anything at all really. And you'll also not have much adjustment. What you might have to do is cut the backstay shorter. It's a little bit less expensive to have the top cut, rather than the 2 legs.
