Had a look through your MOCs - wow! - and wondered whether something like "Rescue Robos" or "Rescue Robots" would work? Bit plain though, and it doesn't cover ALA-N (though a bit of adjustment to his "story" could have him as a space rescue droid, built for orbital and deep-space rescue.
If you were going to do it, I'd suggest a "Thunderbirds" approach. Each "Job Bot" would have a name (which you have already) and a unique minifigure companion, with their own speciality.
The big robo would be the equivalent of one of the larger Atlantis/Dino/whatever sets, and you could offer up smaller "support robot" sets with matching mini-robots (or mini-remote vehicles?) as the equivalent of the small 80-odd piece sets.
The only stumbling block is that the LEGO folks might be looking for antagonists, but you could consider the "Job Bots" having evil counterparts, dedicated to creating havoc that they have to clean up? You could go literal and have a counterpart to FRANK who would be a firebug, or you could go a bit wilder and look at them as just big, destructive droids with unique looks.
