yes
basically gen2 fork bottom and gen1 fork top tube fit together.
1st but
then you need not only the gen2 brake calipers but also the gen2 rims together with the gen2 axle and the brake discs of the gen2,
because the gen1 and gen2 discs have different diameters.
and also the brake lines have to be replaced by new because the angles of the banjos (of the gen1) don't fit the new calipers.
and if you want to change to radial calipers at all, only the brembo from the l3 (2013 and younger) are recommended.
they are a lot better than the tokico from '08-'12.
2nd but
your plan to switch to gen2 sounds to me as if you are not satisfied with the braking performance of the original tokico 6-piston calipers.
in this case i recommend to subject the saddles to a deep cleaning, as i describe on
my homepage
and to repeat this deep cleaning every 30-35 000 km.
usually it doesn't even need new gasket sets according to my dozens of experiences.
that costs alone a few hours and one liter of DOT4 and something else (from MY direct experience on the gen1)
in conjunction with the (often demonized) so-called purely organic pads from EBC, you then have wonderful braking performance and the discs thank you with a much longer life.
these pads alone only last about 20,000 km for ME - then I have to replace them.
AND
if you really want to invest some money in the brake for other components i recommend the 17mm diameter radial brake pumps e.g. the ducati 749 / 999.
with this (and the deep cleaning) one achieves a super fine dosing in the brake, which is unparalleled - so
my direct experience with my own gen1.
costs?
i bought such a used pump for about 150€ here in europe.
good luck
