Thoughts on a glass pack in 1.75" id to connect to a 38mm gate. And no I don't want to route it into the downpipe.

Route it into the down pipe if you want it quieter. Adding restriction in your wastegate tubing sounds like a terrible idea

It has been done in the past without any issues. John's suggestion to up the size makes sense though, no reason not to do that.

If introduced into the downpipe at the proper convergent angle and far enough away from the turbine wheel, depending on the mass flow rate and diameter on said combo the restriction would be minimal.

Again would depend on how much air you are moving through the downpipe and how far downstream the wastegate dump tube is introduced.
