The Wind instrument can toggle only between two info steps: Wind information (direction/speed) and HDWIND/TLWIND. It would be very useful to have a 3rd info step: XWIND (cross wind).

Would you need it to say which direction the wind was coming from, in order to be useful? How would you imagine the reading looking?

I think a speed would be sufficient as whether it is from the left or right is pretty obvious ( or at least easy to mentally judge!). It might be more helpful to indicate which runway the crosswind component applies to.

I think XWIND direction definitely should be included, just like HDWIND/TLWIND. Direction is not necessarily obvious if you make a lot of turns. Direction should be clear by just a quick look.

I still think it is highly preferable to combine mode 2 & 3 so both XWIND and HDWIND/TLWIND are there on the same display, using the Garmin 1000 approach as I suggested. Two arrows take less space than text and are very informative.

Tapping an instrument to have it display different modes is nice, but it becomes less convenient if there are too many view steps. So since mode 1 + mode 2&3 combined display the same information as mode 1 + mode 2 + mode 3, the former is better.
