I like the idea but there is a better hull than the Procurer to use for this ship class, the Primae/Noctis hull was made for this kind of mining at the very least CCPs art department could add a few gas tanks to the model but I think it is there. it is easy enough to set it up with the hard points (as they are already in place on the Noctis) for the current gas miners, so there wouldn't be as much work getting it set for this role, as a guess.

I think it would work well with the folloing:

6 High Slots - 5 miners + slot for probe launcher or cloak,
4 - 5 mid slots - for a tank
3 low slots - for cargo expanders
25m3 drone bay - for defence.

20% reduction of gas harvester duration per level

Role Bonus: 200% better yield for gas harvesters per level

Seriously these attributes would be good as gas mining more than any other form of miing is like watching paint dry getting the mining cycle down to maybe 20seconds and 60m3 yields will cut the mining time, but not too significantly will probably still take a good amount of time to clear a gas site. The other option is up the amount of gas in gas sites .

I think this would work well in this configuration.
