I'm sorry if I've missed something, but isn't the status quo a reasonable option?

Other than that, see what other problems your current customers are having that you could help with. Basically you do not want to leap into a completely new arena and start from zero again (some people can pull this off, most don't). Your Delphi to C# thing appears to be a good example of the sort of transitions you can make.

Alternatively, do personal projects on things related to your hobbies or stuff like that. It's a great of motivating yourself and learning new stuff. Often enough, you will find that there is actually a market for what you built.

Also, find dev meetups in your area (assuming you live close to or in a reasonably-sized city) and go there. You tend to get free pizza and there are always people with interesting / intriguing ideas. Sometimes the people themselves are interesting / intriguing.
