So my S19 did a program somewhat like this. He went to a regional Governor’s STEM school his Jr. and Sr. year for his math and science classes. All these classes were dual enrolled at the local community college but taught on the campus of the Gov school. All the DE classes were weighted like an AP class and considered to be at or above AP level. The math was above since it went past calc BC (MV, LA, and DiffEQ). The science classes gave him more transfer credits than if he had taken the similar AP class/test. He was able to transfer almost all of his credits (+50) from OOS to Ga Tech. He did not get an associates, but entered as a sophomore and will be considered a Jr. credit wise next semester. From the college acceptances that came out of his Gov school class of 81 (every Ivy, MIT, Cal Tech, CMU, GT, Stanford, UCB, UVA, UNC, Duke, WashU, UT-A), I would say that the schools had no problem with classes compared to AP. Now many of the kids took the AP test for their equivalent subject knowing the might not be able to transfer credits.
