wiring headlight help

im redoing my dash and getting rid of the stock switch and making it a push button. would there be an issue with running my instrument lights, marker lights, and head lights off one switch with relays? basically i want to push one button and it turns on all my lights. headlight already has relays. and my markers are all led lights

The point I think is of course you can do it that way, but how you do it will determine how reliable it is.
Since you already have headlight relays you are already part of the way there.
