I have to agree with Dominique here (and I think most people here will consider this as obvious), you never install two version of the same module on the same instance just to have two different version on two different database.
If you want to have two database on one instance, you want the code base to be the same for the two database. If you upgrade the code, you upgrade it for all databases linked to it. If you want a different version for a specific database, you create another instance.
Also renaming the module is a very bad idea. When you git pull a module from Github, an OCA repo for example, you don't want to make any change so you can easily git pull it in the future. If you change the name it means you fork it and it'll be more difficult to maintain. Not even mentioning the fact that changing the name of the module may and will create dependencies problem, bugs, etc... This is not an option.

so why can't you simply rename the module as module(customised) install module on db1 and module(customised) on db2 - they will not conflict.
