I bought my Eleven Rack as a way to play at night through headphones and not turn on my amps or fire up Pro Tools. I haven't played the Helix, but I've been happy with my Eleven, and running my pedalboard in front of it has been even better as well as tweaking the presets.

Not sure which Dr. Z amps you have; I have the MAZ 18 Jr. head and a 1x12 as well as some Fenders; may be worthwhile trying using your amps set as clean as possible first before getting into power amps and new cabs. Yes, sound will be different, but a lot less expensive to test out.

Otherwise, why not sell it and use the funds to get a new pedal, or send your amp back to Dr. Z for updating (will be doing that with mine). You won't get a lot, but it's given you years of service. I try to sell stuff that hasn't been used in my studio or with our band after 2 years...
