Have you considered the NCS540?

It *IS* IOS-XR but I see that as positive, it is more automatable than
IOS-XE on ASR920 in my opinion, it also has fewer and less complicated
licensing in my opinion (in general I mean, not sure about NCS540

NCS540 has a 24x10G with 2x100G uplink combination and a 28x10G with
4x100G uplink combination, that's pretty much how I'd want to replace
my previous usage of ASR920s (24x1G with 2-4x 10G uplinks).

I'd be curious to know if you've had any operational issues that you
share with regards to IOS-XR at the access layer, because it's not
clear to me what you mean by "too heavy".
