Like Jim, I think there's nothing wrong with playing on a CG for morris tunes, especially if you are part of a band, since you are going to be playing the melody an octave higher than most of the other instruments and as Jim says, this will give you greater projection. If you are playing alone, there's nothing wrong with simply playing the tunes in C, rather than G.
I don't quite follow why you say your options are more limited playing in G? G is after all one of the 'home' keys on a CG and in some ways is more flexible and gives you more options than playing in C, not least the fact that you can play the root chord in both directions. You will also find that for many tunes, you are able to keep more of the melody on the RH side if you play them in G, rather than C.
Unlike Jim, I don't find it easy to switch between Jeffries and Wheatstone layouts, probably because I don't do it often. I am however, a passionate advocate for the superiority of the Jeffries, over the Wheatstone layout, especially for the style you want to play. As I see it, the main failing of the Wheatstone layout is the lack of a high d draw which I find indispensable, followed by the middle c# reversal which is very handy on the Jeffries layout. The notes you get in exchange, the high e flat and high f are useful for the odd tune, and I'd certainly go for them on a 30+ layout, but to swap the draw high d for one of these is a very bad trade off. Another problem on some concertinas with Wheatstone layouts is the LH inner row's lowest button draw, which is sometimes tuned to a d rather than an a which again is a poor trade off, since the reverse low a is very useful indeed if you play your own accompaniment. Finally, Jeffries layouts usually have 31 buttons - a LH thumb button, which if tuned to push f, draw c, also gives you a lot of extra chordal and bass run possibilities.
If you use the anglo as a purely melodic instrument, there's probably little difference between the two layouts, but having recently transcribed a lot of my arrangements for players with the Wheatstone layout, I find the logic and ease of the Jeffries system a compelling argument if you want to play with chordal accompaniments.
Since you've only been playing a year, I don't think it would take you long to switch (maybe 2-4 weeks depending on the intensity of your practise?) and I think long term, unless you plan to subsequently get a 30+ layout, I think you'll be thankful you made the change.
I now expect to feel the full broadside of an equally convinced and impassioned Wheatstone layout advocate :-)
