Maraging steels are precipitation hardening steels deriving their strength from the fine particles formed during the aging treatment. Nano-bainite steels on the other hand derive their extraordinary combination of strength from the presence of nano scale width of the bainitic ferrite plate in a matrix of retained austenite. In such a microstructure strain hardening is not the most outstanding property. Indeed therefore that a typical yield and tensile strength of a nano-bainite with eutectic carbon composition containing 1.5 wt% Si and Co are 1.2 GPa and 1.7 GPa respectively (ref Mat. Sci. Forum 2005, 500-501,p495).  Preciptation hardening steels on the other hand can possess highly tunable strengths (see JOM, 1967, vol 19 Nov p60 and Mater. Lett. 2002, 56 p763) with appropriate processing, implying that the strength and strain hardening could be adjusted. Nano-bainite structures are less versatile in the control of strain hardening capacity being dominately dependent on the width of the bainitic ferrite plate. 

You could evaluate the effect of texture on strain hardening. The orientation of the bainitic plates influences strongly plastic deformation and work hardening. I would imagine though a high yield material would give reduced strain hardening. If you want a low yield - high uts material, you would have more upper bainite, while for high yield - high uts (thus low work hardening) you would have lower bainite in your matrix. 

You would find plenty of information on the website of prof Bhadeshia as he's been working on bainitic steels for over 30 years.

It is fundamentally possible by a supplementary approach of suitable change in chemistry influencing controlled phase transformation of fine morphology capable to introduce wide spread barrier to dislocations in the matrix. The matrix should contain strong and hard phases of relevantly fine morphology.
