If you have any suggestions post then in the montly suggestions thread so you get a bigger chance of seeing the items you wish they become available on home
I believe the best that we probably can have is a wannabe costume like the Konami ones. Although Dragon Ball is old, it's still popular and they recently released a new movie, so the demand for the license is probably high and somewhat pricey, which sways away developers of choosing those items from Home. (need to be expired or low price like GE999, Terminator 2, etc)
