Dynamic Resource Allocation

lets say i have a lobby and 2 survival servers (S1 and S2) and i only have 4 vCores in total it would be cool if i can give every server the 4 vCores which are getting shared between all the servers and every server has a lower or higher priority. so depending if more players are on the lobby and the lobby has a higher priority then S1 and S2 the lobby will use the vCores it needs to keep running smootly (for example it needs 3 VCores to run smootly then S1 where only some players are on would only have 1vCore available). i dont know if this is possible or would destroy the concept of the usage of vCores but its just a idea i randomly got so i thought i just share it maybe its good 🤷‍♂️ but this would be great for dynamic resource usage of the resources a server has.
