High frequency use of thyristors
No. The off time is not enough for the thyristor to turn off AND the rate of rise of voltage (dv/dt) is going to be high enough to turn the thyristor on even without gate current. 

Both factors are too high for general-purpose thyristors by at least an order of magnitude. 

Use a MOSFET, a BJT or an IGBT. Or even a relay.
