I think it might be easier and maybe more helpful down the line to make or buy some the 30166 waveguide adapters and keep them stock with a 1.4" throat and then just use a 1" to 1.4" metal adapter.

You might want 288's with tangerine phase plugs down the line as they can get up there and you might be able to squeak by without a super tweeter so I personally would not limit myself by making a 1" only waveguide.

Hope this helps.
