Washing Machine Drain Overflow

I have an older house('62) with 1.5" washing machine drain pipe which overflows. Excellent previous posts informed me that old 1.5" can't handle newer washer flow rates so need to change 1.5" to 2". I opened wall exposing pipe to vent pipe and reducer to 2" tie in(photos attached). I have a few questions before making the change:

1. Can I use the same basic configuration from before the old reducer with 2" PVC?

2. Is it ok to stick with the 1.5" vent pipe? Is it ok to run a short PVC piece up from new PVC T and connect to the old 1.5" vent pipe with a rubber reducer with clamps? (Sorry for what I assume is use of improper terminology). Thanks.
