My guess is 42-63 points, based on 4 factors:
AoYA crossing 12 months = 15-20 points
AAoA increasing 1 year = (say) 5-10 points
Installment loan utilization going to ideal = 10-15 points
6 scoreable inquiries going to 0 = 12-18 points (depends on thier spread across bureaus, though)
This assumes a couple of things are a given. One, no new inquiries. Two, no new accounts. Three, no old accounts drop off, possibly lowering age of accounts if so. Four, no other negative payment history information introduced to your report.
The above doesn't at all take into consideration any current baddies aging, which if thresholds are crossed could help improve your scores even more.
I'm not sure if the removal of a 30D late would have any impact at all on your score with the presence of a (major) BK. Perhaps others can chime on on that. I don't really see anything else you can do other than garden and maintain what you've already got going on. 700+ should be within reach.
