My initial idea (sorry Brian) is to replace the spats with floats so as to make a floatplane fighter.

dont think of it as replacing the spats... just think of the floats as MEGASPATS!

I like!!!

Perfect for use in the Dutch East Indies...later finding a use with the RAAF as some escape the Japanese and operate out of Broome and Darwin...

Some RW D.XXI variations from Secret Projects ...

Fokker D.XXII series concepts

Ontwerp 150 - 1375 hp Bristol Hercules, inward-retracting u/c, 525 km/h
Ontwerp 151 - 1030 hp RR Merlin (chin rad), inward-retracting u/c, 530-535 km/h
Ontwerp 152 - 1090 hp DB 600H (belly rad), inward-retracting u/c, 535 km/h

Fokker D.XXIV concept

Ontwerp 192 - [??] hp Bristol Perseus, inward-retracting u/c, June 1939
 - While the the D.XXII variants were evolutions of the the D.XXI, the D.XXIV was more straightforward - essentially just a Perseus-powered D.XXI with Fokker's preferred retractable undercarriage.

Ontwerp 197 - 425 hp Wright Whirlwind, 2-seat trainer D.XXI deriv., Sept 1939
 - NB: Competition won by the Koolhoven FK-56 (already flying in June 1938).
 -- Ontwerp 197 perhaps something akin to the D.XXI-derived Hispano HS-42 trainer?

Open cockpit, low cut speedster windscreen.
Open cockpit, biplane.
Whatever engine/cowling the MC-200 had, put it on the D.XXI

But whatever you do, don't touch those spats!   ;D

Random idea:  Irish Air Corps D.XXI in scheme similar to this:

Apophenia's secret projects link includes my post on the Finnish prototypes with retracts:
"The first one of the Finnish modifications for retracts was a failure: the mechanism was slow and unreliable, and performance improvements were not realised. The second one (built from the beginning) was a success: the mechanism actually worked and the aircraft gained more speed, and both climbed and dived better. On that one, one pair of machineguns was moved from wings to fuselage, which pilots considered a great improvement - although they thought that replacing the 4 light machine guns with 2 x 12.7 mm ones in fuselage would have been ideal. Unfortunately, there was no time or resources for converting more Fokkers.

And the DXXI with skis, from the Finnish Airforce Museum:
