Here's a quick and dirty analysis.

Results:
Under the old system, the teams combined for an average of 5.33 fouls in the single bonus (one-and-one situation) and 2.78 fouls in the double bonus. Given an average of around 70% FT shooting (so 1.7 FTA per one-and-one), this leads to around 14.6 FTA per game combined for both teams (ignoring shooting fouls).
Under the new system, the teams combined for an average of 5.67 fouls in the bonus. This leads to around 11.3 FTA per game combined for both teams (again, ignoring shooting fouls)
So if there were no shooting fouls, there'd be 3.3 fewer total FTA per game (combined for both teams) under the new rules. I suspect shooting fouls would slightly lower that gap but not significantly.
Given ISU's propensity to not foul (especially at home), this gap is likely higher for other teams. I may find another team that uses the same stats provider and rerun the analysis.
