If you want a counter-offer, how about
Zadorov + Jost for Weegar + 2nd?
With Ekblad/Stralman/Priskie on the right it makes sense to use Mackenzie to acquire a more natural fit at LHD. Zadorov would give Florida a big physical presence on their blueline which they otherwise lack.
Jost would be a young and cost-effective replacement for Haula (who probably leaves in UFA), and showed after the deadline this year that he can do well as a 2C with PP time (3g, 4a in 9 games). Going forward it's unlikely that he keeps getting such opportunities on a deep Colorado team though.
Zadorov and Jost are each probably worth about a 2nd +3rd (2 2nds + 2 3rds total), so it seems fair that Avs get a 2nd back to balance the value. Overall that makes Weegar worth about a 2nd + 2 3rds which seems reasonable.
For Colorado, they would get a steady RHD who can play on the 2nd or 3rd pairing with Girard or Byram. Adding him would make Timmins expendable to be used in a trade for a top 6 forward (eg. Timmins + 1st for Rakell). For reference
here's a capfriendly roster for Colorado based on these moves.
