The wide eartips you got were for TWS, which tend to use shallower tips.
I have the same search going on. Depending on the IEM, I can make various large tips work, usually foam:

Tennmak https://www.aliexpress.com/item/1005003085897631.html
Or for silicones, these BQEYZ, which are shorter but not as short as the TWS tips.

Make sure to leave a message with the Ali sellers that you want all large, not an assortment.
The large, shallow silicone tips that came with my Penon Fan made the Fan sound horrible --I put the Tennmak foams on instead--but they are >14mm and working nicely on a different set of IEMs that were a really tricky fit (RHA-T20i). I've asked Penon about marketing them separately.
If you find something else that works, definitely post here! I'm still looking.
