AMS light rebuild versus aMS 2 Pro

I am seriously considering taking apart my AMS lite and doing a 3D printed modification to the whole system . Basically I’ll be using the model AMS lite 4.0. I was having a lot of trouble with my AMS not feeding filament in properly . Would I be wasting my time printing all that stuff out and changing my configuration for feeding filament into the system ?

The other option would be to just spend $300 us and get the AMS 2 Pro. I don’t really care about the heating aspect of the ams2 pro because I have a poly dryer . Some of the other functions that have changed in the new version of the AMS are appealing to me. But I could save a whole lot of money by printing out all the different components and rebuilding my AMS to a more space conscious configuration.

I don’t want to waste all kinds of filament for something that might not work as well as just buying up brand new thing but I don’t want to just discard the AMS lite. Does anyone have an opinion or other options that I might want to consider
