Conceptually, it should be possible to fit an external VFO and apply speech audio to produce FM; usually phase modulation with an audio freq. correcting network is a common method. Attempting to convert it to ssb would involve a complete re-design, so I don't think that that is a realistic option.
Not that I have listened much on 144 MHz recently, but apparently of the activity that is there, there is virtually zero AM - but I did read a report some time back of a some AM activity on 144 MHz on the South Coast and an enthusiastic group using AM on 70 MHz in South Wales.
So perhaps there is some hope & areas for exploration after all.
