I'd be more concerned about grainbed depth. Should be okay, but you'll have to take extra precaution in vorlaufing in order to not distrub the grainbed.
For example, i suggest using a coffee container lid or something to dissipate the force generated by pouring the first runnings back in. A thinner bed is more sensitive to disturbances.
