I am fairly inexperienced so i may not be the best person to run any ideas past. There are two options I can think of.
One is to write to the editors at the address given in the instructions for solvers, although I suspect they are too busy reviewing, editing and preparing for publication to get involved in too much discussion about early stage concepts.
The second is to try to find an experience setter to talk to. One option may be to contact the ' listen with others' people. If you're not familiar with it, this is a website with blogs written by listener solvers which also contains a blog by the crossword setter talking about how they set the listener most weeks. Just reading the setter blogs may be helpful, but if you contact them they may be able to put you in touch with an experienced setter you could bounce some ideas off.
