I agree with you about the width of the light being important. I carry a thrunite T10 on the inside front pocket. You can see my mods here. Edit: the deep carry pocket clip is also a big plus for me.
It sounds like the D25A is the right size, but it’s not bright enough and the tint is bad? To mod it you first have to take it apart, and this can be the hardest step because some manufactures use glue on the threads. Then I would use a FET+1 driver for use with a li-ion 14500. This will get you a low moonlight and also very bright turbo. Mtnelectronics has some small diameter drivers that might work for your light. Also switch out the LED for one of your choice on the correct size DTP (direct thermal path) MCPCB. Once you get it apart and post pictures we can help with part selection if you’re not sure.
I remember looking at many AA/14500 lights before I chose the T10. As you noticed most are too thick and/or use a side switch. So modding might be the best option to get all the features you want.
