I’m not sure if it’s theoretically not possible, but the “param” part of your link should specify the name of the deeplink, in order to also distinguish it from other deeplinks. After the next “/” you can specify one or more parameters. For the sake of maintainability and (backwards) compatibility I would leave the structure intact :)
This is not possible out of the box. It is technically possible with modification of the source code for the module, but I would not recommend this.
Simpler options are:
Use the constant RequestHandlerName to change link to something shorter say l
Register a request handler for value that redirect to link/value
