Can evs compensate for bad nature?

[zephorous]

I have a modest Suicune which isn't the worst thing in the world, but id prefer bold! Now I know most people run a bit of SpA investment in even bulky Suicune, do you think I'd be able to adjust the EV spreads to compensate for the nature? Such as no SpA investment and put it all in Def instead? I'd prefer not to try and get a new Suicune :P

Thanks!! :D
