Something similar to Vice Squad was being under very serious consideration back when I was Chief. It would have been an investigative division of the VCPD itself to investigate less serious crimes and less important matters (such as investigating suspects that claim they are innocent etc), while the FBI was supposed to be nerfed combat wise and receive improvements in surveillance scripts. Keep in mind at the time we had bigger resources and men power to allocate to such an idea. I believe at this time, it would be impractical and while I do not know, I assume it has been scrapped.
Interiors for hospitals would be awesome indeed. Perhaps it would open way for an official EMS division within VC (Kowalski, pay attention) and for a new route of roleplay to be opened. We could finally have a functional EMS division to actually co-operate with VCPD in dangerous situations like they would in SAMP, rather than bunch of criminals running around in smuggles to heal their mates.
AFAIK VC does not even have a street sweeper vehicle. The current scripted legal jobs are already boring as is. If a new legal job needs to be implemented, it should be made to be as fun and challenging as their illegal counteparts. We need interactivity instead of boring driving around. An actual mechanic job, or firemen duty with scripted fires, in my opinion, would be a better idea.
Ice cream seller just seems impractical and waste of time considering the amount of food bussinesses available. In addition, we probably don't want to create more scripts that would deem other jobs, such as medic, useless.
