I have finished creating a prototype to what I am simply calling Crossword Grid Search which you can find here
https://ugleh.com/gridsearch/(This may be a temporary location, if I do update the location I will apply a redirect)
Grid Search allows you to create a grid with Black, White, and Wildcard squares and afterwards search for grids (currently only from NYT) that share that pattern. From there you can use existing grids as a base for inspiration. Along with searching for the grids you can then click on an image to be taken to the XWI page of that crossword.
Please share feedback and suggestions, thanks.
