Of course you can do this. But why use a Envelope: much more interesting
should be the Sequencer to modulate this VCA. Alternatively you might use
the sequencer clock to trigger a S&H which is fed by a fast LFO. This
results in a renadom like, but nevertheless regular repeating sequence.

BTW: controlling the linear-FM Input with the Sequencer is not that
sense-making, since this input is DC decoupled. You will have a kind off
glide effect to and from the Sequencers tuning back to the standard tuning
of the VCO.
