I think you would have problems creating one, because even if you nailed the sound precisely, the people that want tube amps would reject it as sounding "too digital". The reason people choose tube amps isn't necessarily about sound.

The reason tube amps have the sound they do is audible distortion.  High fidelity solid state amps have distortion figures that are well below the level of audibility.  You can certainly create a gushy warm sound with equalization but it still won't have the audible distortion of the tube amp.  To get true tube sound from a solid state amp you would have to introduce harmonic distortion into the circuitry on purpose.  Carver tried to to do that once but the amps were still indistinguishable from other sold state amps in bias controlled comparisons.
 
Basically if you like tube sound, you need a high distortion tube amplifier.  Even low distortion tube amps are indistinguishable from solid state amps in bias controlled tests.

Basically this post explains all. Thanks.
