My KSK and ZSK are both of algorithm 8 and 2048 bits in size.

Is it correct to assume that -due to the growing adoption of algorithm 13- that this algorithm should be preferred? 
If so, I would like to migrate. 
But, I do have some questions to the community beforehand:

#) Can one mix KSK and ZSK algorithms? 

   (I do have a rollover of my ZSKs due in a couple of days. Thus starting with ZSKs would be convenient.)

#) Would it be wise to increase from 2048 to 4096 bits size?

Thanks in advance and with kind regards,
Michael
