The limits of reengineering lies in how far you can break down the processes composing a given phenomenon and how finely you can tamper with their inner mechanisms. These two sides are virtually unlimited when it comes to Lawrence's expertise and abilities, so there is probably no such limits for him (unlocking endless options by breaking it down indefinitely).

For more details, see the quote below from a well-written past comment :

"Imagination is inherently based on knowledge, and it's particularly true for Lawrence. His imagination operates as the simulated reengineering of the empirical data he previously memorized (see the "Possibility Matrix" section), so it cannot be used to create anything truly new since any imagined being/item is entirely based on 100% accurate information.

On the other hand, he can instantly, perfectly and retroactively memorize any phenomena on every level in its most infinitesimal details. Combine that to his truly limitless processing capabilities, and he can effectively retro-reengineer virtually anything into anything else, instantly breaking down a dust grain into a primordial soup of sub-quantum proto-particles, and masterfully re-evolving them into a thousand universes worth of brand new possibilities.

So while Lawrence cannot create new information from nothing, his reengineering expertise is so incredibly advanced he can forge nigh-infinite possibilities from any material available."
