Correct feeling :-).  Set up 6 groups.  Let's suppose groups 1,2,3 
are pp, mf and ff long samples, and groups 4,5,6 are tremolo pp, mf 
and ff respectively.

In group 1, set 'Select range' to 1-40, in group 2 set this to 41-80 
and in group 3 it's 81-127.  Do the exact same for groups 4-6.  This 
will give you velocity crossfading between dynamics.
Then in groups 1,2 3, in the first 'Select by' slot, pick 'Ctrl' and 
'1', and in the 'Ctrl Range' slots enter 0-63.
In groups 4,5,6, also set 'Select by' to Ctrl 1, and set the 'Ctrl 
Range' to 64-127.

Save the instrument, close the Instrument editor, and in the EXS 
interface dial in a non-zero value in the 'Amount' field (left side 
of the window, right above the 1st modulation matrix thingy).  This 
value determines the amount of crossfading.

Now finally deal with the first modulation matrix slot.  Make sure 
Dest is set to Sample Select, 'via' is empty, and Src is velocity.

Now when the modwheel is between 0 and 63, you'll be playing the 
velocity xfaded long samples, and with modwheel between 64 and 127, 
you'll play the velocity xfaded tremolo.

I don't know how well this will sound though.  In my experience, 
velocity xfading natural instruments tends to give a kind of 
"doubled" effect in the xfade region, instead of the intended gradual 
fade.  And note that the above setup does _not_ provide an xfade 
between regular and tremolo samples.  It's unfortunately not possible 
to have 2 different kinds of crossfades happen simultaneously.  Would 
be possible with some basic environment patching, but that's a 
different story....
