Creating a new identity for Lazarus is tricky business.
You are aware, that so far none of the developpers want a new logo or splash screen.
And that the argument of modern/trendy/etc has not made a difference to it.
Further more attributes like modern/trendy are usually set by advertisement (like white earplugs for mp3 -- who would have thought of white before).
Only in rare cases something catches on as trend without the need of a campeicn.
Since we can not pay a campeicn ourself, we have 3 options:
- leave it
- copy / lean-on somebody else's design (IMHO not good)
- create a random NOT YET trendy image, and hope to win the lottery
Let's take the existing tokens separately.
The cheetah and the paw can apply to : animal care, animal shelter, safari trips.
The Greek column can apply to : history, architecture.
The cog can apply to: engineering.
The Lazarus name has religious and metaphorical meaning.
Putting those together, the splash screen created a now known association, by telling a story.
Strange, I never read any story into the splash screen.
I also have in most cases other associations entirely.
e.g. in the cheetah I see a dominant element (top of the food chain / king (despite that word is usually associated to lion) of it's environment.
Cheetah on TOP of a column: amplifies this / deity like
Therefore the splash screen immediately gave me the appearance of a product that is a major player.
But, yes I see that people con read different stories into a symbol. The old window flag, with 4 colors somehow reminded me of a circus (not sure why). Tell that to microsoft, they will be exited (the new one 4 color-less panels, associates tiles in a bath room...
I never really read anything into the name (it was just a name) until I read the history.
In todays world many names are NOT associating the product to the original meaning of the word (I never thought to do my grocery shopping in an apple store), And with other names there is a meaning, but you need to read up, to get it. (eg they are abbreviations like BMW and not everyone knows the full meaning)
I'm not sure this story can be easily expressed by a minimalistic design.
The cheetah in a cog, visually, doesn't have what it takes. The same goes for the paw in a circle.
Cheetah on a pole, the word Lazarus with the red band bellow, these don't fit the description either.
So, the related logo, as it is the case with Windows, Apple, Android, Ruby, it's out of the question.
How do an
- apple
- penguin
- flag with 4 colors (then circle with 4 colors, now 4 panels (wtindows)
associate with an operating system at all?
They are random symbols, later associated to a product
Our current logos and images are not one bit less.
What's left is searching for an abstract and catchy design, the same as Mac (faces), Linux, PostgreSQL.
The paw and coq are exactly that
The task isn't easy, but, it seems that Lazarus is already on the path on searching a stronger brand. All it's left is the patience and the hard work. 
Again, before you go on a search: Convince those who will decide, that it is needed.
Otherwise you can find whatever you want, it will not do any good.
I am NOT convinced.
I have not seen any one else of the developer team indicating that they are.
-------------------
What may need to be done, is to collect the CURRENT identity, document it, and ensures it is always applied.
Like ensure, we use the same (the CURRENTLY used one) font for the word lazarus in all places.
