What you propose is easily accomplished with many Arisaema species to 
reduce the time from seed until first flower to within two years. I 
think this is very possible for Erythronium as well, but one concern 
is not knowing how long to maintain the bulbs at warm temperatures 
after the leaves die down before beginning vernalization. Given the 
natural range of E. multiscapideum (PBS wiki lists as E. 
"multiscapoideum"), there is a possible minimum time requirement for 
warm dormancy, which likely varies with temperature, before the bulbs 
can perceive vernalization. While there is some literature on this 
topic for other species (especially Lilium), I can't find any 
dormancy info for Erythronium. As for vernalization, ten weeks at 5C 
has been reported to be the optimal vernalization period for 
Erythronium 'Pagoda.'
