If I was planning on re-doing a kitchen in 2-3 years I would try and make the best of what I had for the next 2-3 years. By the time you've got wood cut to size (current situation would delay this I suspect) got them fitted (also delayed right now) or fitted them yourself it would be 6 months or more down the line.
From a quick google the Somerton range is inset, so whatever doors you get you're still going to have the frame of the cabinets exposed - how would you deal with that colour irregularity if there was one?
On the Magnet website the Somerton range is listed as "Framed painted solid timber" - doesn't that mean it could be sanded back and painted? I would maybe give Magnet a shout to see what their interpretation of painted solid timber is.
