Thanks a lot! I will do it as what you suggest!

If I were you, I do as follows:
A feature vector consists of static, delta, delta^2 features as
c(1),..,c(25)
delta-c(1),..,delta-c(10)
delta^2-c(11),..,delta^2-c(25)
First I train HTS using this feature vector.
And then I add nuisance dimensions as
c(1),..,c(25)
delta-c(1),..,delta-c(10),*delta-c(11),..,delta-c(25)*
*delta^2-c(1),..,delta^2-c(10)*,delta^2-c(11),..,delta^2-c(25)
where *...* denotes nuisance dimensions.
If I set all inverse variances and means in nuisance dimensions to 0,
they are not taken into account in the parameter generation algorithm.
By running HMGenS with appropriate window coefficients,
you can obtain proper outputs equivalent to what you really want to do.

Yes, but you may need to turn off some consistency checks for dimensionality in HGen.c and HMGenS.c.
