Podzipping is removing unneeded stock files or repetative custom files from a pod to minimize it's kb size. Podmerging is combining more than one track or truck pod list into a single pod file. I think you meant to say podmerged.
Merging pods for your own personal use is perfectly fine so long as you keep it to yourself, but, if you upload it here or anywhere else to share with others it will result in complaints 99.8% of the time unless you first get the permision of all the authors before uploading anywhere.
I know you meant no harm in your idea, in fact I think it was a very good idea except for your approach. In the future simply post a list of available favorite mtm2 trucks that fit a real or fictional monster jam lineup, then post the list here for others, complete with links to all the trucks.
If the idea flies we can set up a truck 'favorites' list like are available for tracks.
like so >
