Sure, but would also render their Suppression rule worthless.
given that lastalons have boltgun range, the mobility of the surpressors would pretty much be indispensible if that were the case
It may not have much value around these parts, but even GW wouldn't abandon a special rule like this.
*cough* Flamer Aggressors *cough*
Also the suppressing special rule would work with Las Talons just as well as with their Autocannons. Probably better even as you'd have a higher chance of actually killing a model. In fact the Las Talon would outclass their autocannon in everything except for range so that's probably a better reason why they are unlikely to get such an option. ^^
You’re forgetting points, a Lastalon costs 40 pts. I am not arguing against that just pointing out that for a mere 25pts per model you get a badly needed anti-tank unit that can still do its original job better.
Just to point out again that I think giving suppressors an onslought gatling gun is a “bad” idea, for a mere 6 pts per model difference you effectively double the units ability to cause casualties to low toughness units, the math even works out that your more likely to stop a Primaris squad from shooting with OGCs than the Autocannons Suppressors currently have.
