Its probably possible but may be a pain in the neck. My Whites will eat moths, earthworms, anoles, and geckos. So you may find yourself having to catch a lot of bugs, having to be absolutely certain which ones aren't inherently poisonous or exposed to pesticides. And then you have critters other than crix in your house, which probably was not the point in the cricket ban.
And don't count on being able to hand-feed (tong-feed) any Whites TF easily or immediately. Some can resist learning that trick for years.
