Ok ...
So ... The first good thing would be tho have access to the base of the phototransistor ...
just to make it less sensitive ... ( you've correctly read ).
Second ... SPEED ! Opto transistors really are lazy components ... I just dig into my docs to find an old 30 Years old Motorola scheme intended to make performances acceptable ...
Also consider Honeywell HOA 901 or equ. components ... worth the try.
Third: encoder Wheel ... did you try the transparent Polyester film for Inkjet Printers ???
... that's what I use for my PCB UV Exposure !!!
read you soon
