Hi and welcome to Subsim
Most of the major mods have removed the xhairs and there is probably a single mod out there to do it
If you want a step up in game play and want to try one of the "super " mods
then you have a choice of 3 really these days
UWAC 2 -

NYGM 2.3 is the latest I believe
And of course GWX -

None of them will work together but you can have multiple installs and try them all out
All of them add something extra to the game - but none more so than GWX
And dont forget SH3Commander -

A great program that no SH3 gamer should be without
